Clinical dilemma in the management of an unstable spinal fracture in a frail older patient with multiple comorbiditiesconservative versus non-conservative care. A case report| JOURNAL OF GERONTOLOGY AND GERIATRICS

Abstract

Significant dilemma exists in literature regarding the management (surgical vs conservative) of elderly patients with significant comorbidities presenting with spinal injuries. An 82 years old female patient with significant comorbidities and a background of ankylosing spondylitis presented with unstable fractures of the thoracic spine. Multidisciplinary team approach with medical optimisation, early surgical intervention followed by rehabilitation was offered to her. She made an uneventful recovery and returned back to her baseline mobility.

INTRODUCTION

An 82 years old female patient with known ankylosing spondylitis was transferred to the regional spine unit with an unwitnessed fall. She had a significant past medical history of Alzheimer’s dementia, chronic kidney disease (stage 3), bronchial asthma and scored 7 out of 9 on the Rockwood Clinical Frailty Score. She had sustained an unstable neck injury two years ago, which was managed conservatively as she was deemed to be high risk/unfit for surgery.

She lived alone with carers four times a day and was able to mobilise independently with a frame indoors. The CT scan of her spine revealed unstable fractures at T5-6 and T11-12 levels with translation of the spinal column at T5-6. Managing her with a brace this time around would have been practically impossible because of the nature of the fractures, the number of levels involved and the potential risk of cord injury with further translation of the spinal column. Her case was discussed in the multidisciplinary (MDT) meeting comprising of the spinal surgeons, ortho-geriatrician, anaesthetist, intensivist and patients’ relatives (who had lasting power of attorney). It was decided that surgical stabilisation was the best possible option for her after medical ortho-geriatric optimisation, with the proviso that critical care bed would not be offered to her post-operatively.

Following the discussion with the anaesthetist, it was decided that the surgery should be done in the shortest possible time duration, as she was unlikely to tolerate prolonged anaesthesia. It was decided to operate her T5-6 facture as a priority as it was more unstable, and to proceed to the lower level based on how well she tolerated the first half of the procedure.

She underwent T4-7 open posterior stabilisation along with minimally invasive T10-L1 posterior stabilisation with pedicle screws and rods (Fig. 1). Minimally invasive procedure could not be used for the upper levels due to inadequate visualisation on the lateral flouroscopy and in view of significant translation of spinal column at that level. The surgical duration was 2.5 hours and the blood loss was around 400 mls. Postoperatively, she had significant improvement in her pain scores. She was able to sit out for her meals within 24 hours after surgery, and at 36 hours able to mobilise a few steps. Her catheter was removed at 48 hours and able to mobilise to the toilet by day 5.

DISCUSSION

Patients with AS are at high risk for spinal fracture when compared to the general population due to their stiff spine with long lever arms and underlying osteoporosis ¹. Cervical spine is the most commonly involved level. CT scanning of the entire spine is essential in these cases as many of the occult fractures can be missed in plain radiographs and MRI imaging ².

Conservative management of these fractures is associated with significant problems including skin ulcerations, chest infections, delirium and loss of muscle mass due to a prolonged immobilization with brace ³, however the risk of surgical intervention also remain high.

Multidisciplinary team approach with medical optimisation, early surgical intervention followed by rehabilitation is considered the ideal treatment for older people with significant spinal injuries. Ortho-geriatric care has emerged as a collaborative care model between geriatricians and orthopaedic surgeons for older adults hospitalised with hip fracture ⁴. A national survey has shown that increasing ortho-geriatrician time spent per patient from 1.5 to 4 hours, resulted in reduction in time to theatre, with an overall 3.4% decrease in 30-day mortality ⁵. Since the inception of ortho-geriatric care, most of the published research in this field has examined its application to patients with a hip fracture, which is unsurprising given that hip fractures cause significant morbidity and mortality, along with substantial healthcare costs. However, spinal fragility fractures are common in older people admitted to hospital and we have shown that collaborative involvement between ortho-geriatricians and spine surgeons may also lead to an improvement in patient outcomes.
